In 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves. Credit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet.Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna.n 1932, Karl Jansky at Bell Labs revealed that stars and other objects in space radiated radio waves.

Z-Wave is a wireless communications specification designed to allow devices in the home (lighting, access controls, entertainment systems and household appliances, for example) to communicate with one another for the purposes of home automation.-Wave is designed to provide reliable, low-latency transmission of small data packets at data rates up to 100kbit/s, unlike Wi-Fi and other IEEE 802.11 -based wireless LAN systems that are designed primarily for high data rates. Z-Wave operates in the sub-gigahertz frequency range, around 900 MHz.
